11.02 DAQ continues OK Current file May2017/R22_192 ASIC settings 2017Mar27-16.12.39 except slow comparator 0x0a LEC/MEC fast comparator 0xff Detector biases; leakage currents OK - see attachment 1 FEE64 Temperatures OK - see attachment 2 good events; statistics OK - see attachment 3 No warnings/errors reported by merger since DAQ GO - see attachment 4 all system wide checks OK except ADC calibration of nnaida7, 9, 13, 22 11.05 E17/F11 ambient temperature +23.9 deg C, RH 41.3%, d.p. +10.5 deg C Julabo FL11006 set point +20 deg C, actual +20.0 deg C, water level OK (c. 75%) Voltage on BRIKEN 3He tubes now ON 11.07 DAQ stops OK Current file May2017/R22_193 Deleted R22* Loaded new firmware to test ADC calibration clock issues - attachment 6 Firmware loaded - attachment 7 Restarted Firefox - temperatures still look fine - see attachment 7 System wide checks - nnaida1 clock failed, other clocks OK - attachment 8 ADC calibration failed for nnaida1, 3, 21 - attachment 9 Other system wide checks OK Statistics - few SYNC pulses received by nnaida 9 and 12. See attachement 10 ASIC settings 2017Mar27-16.12.39 except slow comparator 0x0a LEC/MEC fast comparator 0xff BNC PB-4 settings Amplitude 90,000 x5 attenuator IN t_r 50ns, tau_d 50us polarity - rate 250Hz range delay MIN, tail pulse 13.10 DAQ started File May2017/R23 Run Control GO - Tape server GO - Merger Unpause - Merger data rate 0, but Tapeserver sees events and Merger links are green - see attachment 11 Start ASIC data readout - Merger sees data rate of ~800 000 items/s (OK!) FPGA clock monitor page (http://localhost:8015/AIDA/MONLOCK/MONLOCK.tml) screenshot attached (12) Ras Pi system console logs for USB0 attached - see attachment 13 18.00 Merger found stopped. We were unable to stop the DAQ. Powered off FEEs. Power on, only eight were supplied power. Blown fuse in USB bias controller - replaced. Power ON the FEEs. All 24 FEEs mounted. Current file May2017/R23_27 - stopped at 15:27 18.31 nnaida20 rebooted on its own 18.37 E17/F11 ambient temperature +23.7 deg C, RH 39.8%, d.p. +9.5 deg C Julabo FL11006 set point +20 deg C, actual +20.0 deg C, water level OK (c. 70%) 18.41 Restarted DAQ Detector biases; leakage currents OK - see attachment 14 System wide checks - OK except several modules failed ADC calibration - see attachment 15 FPGA clock monitor screenshot attached (16) 18.51 Stopped DAQ. Flashed previous firmware on FEEs (FEE_GF_Feb16_24.bin) Power cycled. All 24 modules mounted OK. nnaida22 rebooted on its own Time out Setting up the DAQ on nnaida2 and others. Power cycled again. nnaida17 rebooted on its own. Time out Setting up the DAQ on nnaida1. Power cycled again. 19.56 DAQ finally started. Current run R24 ASIC settings 2017Mar27-16.12.39 except slow comparator 0x64 LEC/MEC fast comparator 0x20 all system wide checks OK except some ADC calibrations and clock on nnaida1 Temperatures OK Statistics OK Logs for nnaida 17,20,22 attached Encoding: HTML ELCode plain Suppress Email notification
